Supprts TTL level communication with an option.
< Image of Use >

With an optional TTL probe pod (OP-5M), it can monitor TTL-level communication at 2.5V/ 3.3V/ 5V. It is useful such as when measuring TTL signals on an UART port of PCB and communication units.

Support Async PPP communication

Support Async and PPP communications. It is possible to select bit transmission order, polarity, and data format (NRX/NRX) and able to analyze efficiently.

Trigger Configuration (Example 1)

In this setting, if finding an error, “1” will be added in the “Conter1”. Details of counters can be checked by selecting Timer/Counter window. And, the value of counter can be another trigger condition.

Trigger Configuration (Example 2)

In this setting, if finding data of “41h, 42h, 43h, 15h”, LED of U1 will be lighted. It is useful to check the flowing of specific data on the line without stopping the measurement.

Lights of LED stands for:
POWER/ERROR Indicate the operating status of analyzer
.
RUN/ACT Indicate that analyzer is measuring or accessing to the SD card.
SD/RD Indicate the status of SD line (green light) and RD line (red light).
U1/U2 Able to light the U1 (green) /U2 (red) by trigger actions.
Long Hour Recording

[Recording Time]

Baud Rate

Capacity: 2G byte

(e.g. 2M byte×100 files)
9600bps Approx. 120 Hours
230.4Kbps Approx. 5 Hours
*: In the case of full-duplex transmission of 1Kbyte data at 1ms interval.

Measured data is saved as log files of the specified file size in the HDD of the PC (Remote mode) or in the SD card of the analyzer (Logger mode).

It automatically records data until reaching the specified number of files, and then deletes the oldest file to record the new file. Also, it can stop measurement on reaching the specified number of files. It is useful for detecting any hindrance in the line.

<Record Control Setting in Remote mode>
<Record Control Setting in Logger Mode>
Measures at Arbitrary Speed

Monitor data at any speed by setting the baud rate of any four digits.

The high-precision timer makes it possible to record idle time and time stamps along with data, and is not related to the performance of the PC.

<Configuration Setting>
Easy-to Operate Simulation Function

It incorporates an easy-to-use simulation function that makes it possible to transmit preset transmission data (16 types of data), or fixed data such as FOX messages, at the flip of a key while checking reception data.

<Example of Simulation>

Schedule Measurement by Inner RTC

Real Time Clock (RTC) backed up by the battery of the analyzer makes it possible to specify the starting and ending times of the measurement. After the measurement, it turns off the power automatically and saves on power consumption.

<Auto RUN/STOP Setting>
Example of Use 1
<Configuration of Example1>

Measure while the factory runs operation from 9:00 to 17:30.

Saving Mode Append

Run Time 9:00
Stop Time 17:30
Power On Run off

LED of LE-150PS will start blinking at 8:59 and be ready for measurement. It will start measuring at 9:00 and record data in the SD card for 450 files (4M each) as a ring buffer. It will stop measuring at 17:30 and turn off the power automatically to save on power consumption.

 

*   LE-150PS will start measuring from the next day if configuration is set after 9:01. To start measuring soon after the configuration, select the “Power On Run”.
*   If the trigger action (stop measurement) is satisfied, LE-150PS turns off the power automatically to save on power consumption.
Example of Use 2

 (safety start)

In this care, it is necessary to prove power to the LE-150PS from the same power supply for the equipment.

Safety start will start measuring approximately 40 seconds (LED will be blinking) after powering on the analyzer for charging the capacitor for back-up data.

Communication logs will be saved in the SD card for 500 files (1M each) endlessly. LE-150PS will stop measuring when the power is not supplied for more than 1 second after saving data in the SD card.

 

*   To record data soon after the power is supplied, select “Quick Start”. However, it is possible that SD card will be damaged from power failure.

 

Seamless Access to Communication Log Files
<Text Conversion Setting>

Communication log files can be viewed in detail on a PC. It offers seamless operation that handles a single measurement log file even when all files are read collectively. The measured data can be converted into text or CSV format to use in a word processor and/or spreadsheet software.

Control multiple analyzers by one PC software.

PC link software (LE-LINK20) included with the product controls multiple analyzers at the same time, and displays data in the separate measurement windows.

Can be used in Various Situation

Protects Important Data from Corruption due to Power Failure

A newly developed Instant Power Failure Prevention circuit with a Super Capacitor protects important communication log files stored in the SD cards. It protects data in case it occurs the power failure during recording to the SD card. Also, you can select the restart method of measurement from "Instant Start" or "After Charging Super Capacitor". Thus, continuous recording is possible while considering the status of data generation and power system.

[Acquired Patent in Japan]

Small and Robust Housing Suitable for Severe Field Environments
< Dust-proof covers >


 < DIN Rail Installation Example >

The palm-sized robust unit can be used between –10 to +55°C. It operates not only on USB bus power, but also on external DC power of 8 to 26.4V. The consumption current is as low as 100mA at DC12V input. The SD card slot and the USB connector are equipped with a dust-proof cover that allows 2-way operation. It can be fixed easily to the equipment to be examined or built into an inspection line, since it is compatible with 35mm DIN rails.

Automatically Switches between Japanese and English

The system language alternates automatically between English and Japanese according to that of OS. This facilitates introduction of the software to development bases outside Japan.
